IMPROVEMENT IN` MACHINES FOR TENONING SPOAKES.

Specification forming part of Letters Patent N0. 59,420, datedNovemberv, 1866.

To all lwhom 'it 'may concern:

Be it known that I, JOSEPH LETTEREL, of Union, in the county of Pike andState of Indiana, have invented certain new and useful Improvements inMachines for Tenoning Spokes and Boring Fellies; and I do herebydeclarethat the following is a full, clear, and eXact description of thesame, reference being had to the accompanying drawings, andtothe lettersof reference marked thereon.

In the annexed drawings, making part of this specification, A representsthe frame of the machine, which is made of timber and in a substantialmanner. B represents a carriage, which slides upon ways properly securedupon the frame A. B B represent two standards which are erected upon thecarriage B. C and I) represent cross-pieces, which are firmly secured tothe standards in the position represented. E represents a shaft, whichlies across the two cross-pieces D, said shaft being provided withjournals, which rest in suitable journal-boxes in said cross-pieces.- Frepresents a gear-wheel upon shaft E, which meshes into a gear-wheel, G,upon ashaft, H, which said shaft has its bearings upon the cross-piecesC C.

Upon one end of shaft H is awheel-shaped hollow bit. This bit has a holeat its center and knives (two or more) on its face, running from theperiphery to the hole at the center. This hole in the bit is just largeenough to receive the tenon on theend of the spoke, the knives servingto cut away the wood on the end of the spoke, so as to form the tenon.

J represents a shaft, which lies crosswise of frame A, having itsbearings in said frame. This shaft has a lever-handle, K, upon one endof it, and about center way of it a gearwheel, L, which said gear-wheelworks into the teeth of a rack-bar, M. The rack-bar M is secured to theunder sider of the carriage B. By raising or lowering the lever-handle Kthe Wheel L is partially revolved, and the carriage B is thus movedbackward or forward on the frame A by the wheel working in the rackbarM.

N represents a shaft with a thread cut upon it, which lies lengthwise ofthe frame A and under the carriage. This shaft has a nut, O, upon it,and this nut serves to arrest the progress of the carriage as itl movesin one direction upon the ame.

P represents a vertical shaft secured at one end of the frame A. Thisshaft has a thread cut upon its upper end. A nut with a handle,

Q, to it passes over the thread on this screw.

In using this machine for tenonin g spokes, the hub of the wheelcontaining the spokes is placed over the shaft P, said shaft runningthrough the opening for the box in the hub. The nut is placed on the topof shaft P and screwed down, holding the hub tight in its place on theshaft. By means of the handle K the carriage, with the bit I, is run uptoward the spokes. The bit is set inV motion (revolving) by the handle Son shaft E. The end of one spoke passes into hole X on bit I as theknives on said bit cut away the wood, forming the tenon. The nut O isset so as to stop the carriage when the tenon has been cut long enough.When one spoke has been iinished the carriage is moved back a little andthe hub turned,- so as to allow the next spoke to be cut by the bit,which is operated upon in like manner as the first, and so all of thespokes are'tenoned.

In order to bore fellies the shaft H is removed from wheel G and theauger U inserted,

which is both an4 auger and a shaft. The wheel is removed from shaft P,and the frame,

composed of the arms T, cross-piece W, and

keeper Z, is placed over the shaft P, said shaft passing through hole Vin said frame. The felly, bent in proper shape, is placed upon thisframe and secured down by the nut of shaft P. The carriage is then runup with the auger U, which bores the hole in the felly for vthe tenon ofthe spoke. Hubs or blocks with holes in them are first placed over shaftP, in v order to raise the frame to the proper height for the auger.

Having thus fully described my invention,"

A bit-and boring apparatus with shafts P and N, movable frame B', bymeans 'of the rackbar M, leverhandle and wheel, constructed upon asuitable frame, A, when arranged in the manner and used as and for thpurposes herein described.

As evidence that I vclaim the foregoing I have hereunto set my hand inthe presence of two witnesses.

JOSEPH LETTEREL.
